NOAA/WDS Paleoclimatology archives a tree-ring width chronology from Colorado, United States. The data provides annual-resolution climate proxy records covering the period from 750 to 37 calendar years before present (BP). This dataset was created by the NOAA National Centers for Environmental Information and was last updated in 1987.
Use Cases
- Reconstruct historical precipitation and temperature anomalies in Colorado using the tree-ring width series.
- Calibrate climate models by comparing the tree-ring proxy data with instrumental records for the region.
- Analyze the frequency and severity of past drought events from the annual tree-ring width measurements.
- Study the response of tree growth to climatic forcing over a nearly 800-year period ending in 37 BCE.
Strengths
- Provides annual-resolution climate proxy data spanning approximately 787 years.
- Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI).
Limitations
- Data coverage ends in 37 BCE, offering no records for the modern instrumental period.
- The dataset was last updated in 1987, indicating potential staleness in metadata or documentation.
